My academic and professional experience

• About me

I don’t know what to say first, but I need to leave some text and pictures here, so I leave a poem:

My steadfast lover, true, with no regret’s sound,

Hear my whisper soft as your eyes lead the way—

Ahead, dark thorns and mires do abound,

Yet dreams of splendor past, behind you lay.

Here are three plots

First, load necessary packages:

library(p8105.datasets)
library(flexdashboard)
library(plotly)

## Loading required package: ggplot2

## 
## Attaching package: 'plotly'

## The following object is masked from 'package:ggplot2':
## 
##     last_plot

## The following object is masked from 'package:stats':
## 
##     filter

## The following object is masked from 'package:graphics':
## 
##     layout

library(dplyr)

## 
## Attaching package: 'dplyr'

## The following objects are masked from 'package:stats':
## 
##     filter, lag

## The following objects are masked from 'package:base':
## 
##     intersect, setdiff, setequal, union

library(tidyverse)

## ── Attaching core tidyverse packages ──────────────────────── tidyverse 2.0.0 ──
## ✔ forcats   1.0.0     ✔ stringr   1.5.0
## ✔ lubridate 1.9.2     ✔ tibble    3.2.1
## ✔ purrr     1.0.2     ✔ tidyr     1.3.0
## ✔ readr     2.1.4

## ── Conflicts ────────────────────────────────────────── tidyverse_conflicts() ──
## ✖ dplyr::filter() masks plotly::filter(), stats::filter()
## ✖ dplyr::lag()    masks stats::lag()
## ℹ Use the conflicted package (<http://conflicted.r-lib.org/>) to force all conflicts to become errors

Importing and cleaning the dataset:

data(ny_noaa)

ny_noaa_subset <- ny_noaa %>%
  filter(!is.na(prcp), !is.na(snow), !is.na(tmax), !is.na(tmin),date>="2010-01-01")

Scatter Plot (Date and Snowfall)

plot_ly(ny_noaa_subset, x = ~date, y = ~prcp, type = "scatter", mode = "markers") %>%
  layout(title = "Date vs. Snowfall in 2010",
         xaxis = list(title = "Date"),
         yaxis = list(title = "Prcp"))

Barchart (Date and Precipitation)

agg_data <- aggregate(ny_noaa$prcp ~ format(ny_noaa$date, "%Y"), FUN=sum)

plot_ly(agg_data, labels = ~format(as.Date(ny_noaa$date, format="%Y-%m-%d"), "%Y"), values = ~ny_noaa$prcp, type = 'pie') %>%
  layout(title = 'Total Precipitation per Year')

Bar Chart (tmax and tmin)

plot_ly(data = ny_noaa_subset, x = ~id, y = ~snow, type = 'bar', colors = 'viridis') %>%
  layout(title = "Snow amount in 2010 per location", xaxis = list(title = "location"), yaxis = list(title = "Snow amount"))
